Re: Limp mode, '97 2500 454 Suburban
What is limp mode, and what are the symptoms?
Typically a fuel pump on its way out works better with the tank full of fuel and before it heats up. Easy to test fuel pressure at the port with a gauge. What is the condition of battery cables, your grounds, when was the last tuneup?
